Distribution |
Western Pacific - known from Western Australia and the Philippines. Records from the Northern Territory may be misidentifications. |
|
Features |
Dorsal fin VII + I, 9; Anal fin II, 8; Caudal fin, principal rays 9+8, branched rays 8+7; Pectoral fin 15; Pelvic fin I, 5; Vertebrae 10+14=24; Gill rakers 22-24. |

Colour |
Colour in life unknown. Body presumably transparent like other closely-related species, with a dark bar from the tip of the lower jaw and snout to the eye; a silvery white band along side, tip of spinous dorsal fin black; caudal fin margin dusky; peritoneum silvery-white; stomach jet black (Fraser 2012). |

Biology |
Almost nothing is known of the biology of this species. Like all apogonids, males brood the developing eggs in their mouths. |

Similar Species |
Ostorinchus atrogaster differs from O. aphanes in dentition, and in having a silvery line running above the lateral line to the base of the caudal fin (Fraser 2012). |
